Is it imprudent for Rauf and his supporters to locate the proposed Islamic center so close to the site of terrible violence against Americans committed in the name of Islam? In fact the fault lies less with Rauf than with a debased effort to whip up partisan fervor around the issue. Must Muslims unequivocally reject all forms of terrorism—especially those Muslims who wish to promote full Muslim participation in American society? Of course. But if the Catholic experience in the United States holds any lesson it is that becoming American also means asserting one’s constitutional rights, fully and forcefully, even if that assertion is occasionally taken to be insulting. The genius of the American experiment in religious liberty is precisely this long-term confidence that equal rights for all religious groups build the loyalty every democratic society needs. Certainly American Catholics learned that lesson long ago.
